PET Short Fiber Needle Punched Nonwoven Geotextile

Describe

PET short fiber needle punched nonwoven geotextile is a geosynthetic material manufactured from polyester staple fibers through processes such as opening, carding, web forming, and needle punching. It offers excellent tensile strength, tear resistance, and durability. This material is widely used in infrastructure construction such as water conservancy projects, highways, railways, ports, and tunnels. It serves multiple functions including reinforcement, separation, drainage, filtration, and protection. The product has high water permeability and outstanding resistance to chemicals, ensuring long-term performance even in harsh environments.

Basic parameters

Features

• High strength,Due to the use of plastic fibers, it maintains sufficient strength and elongation both in dry and wet states.
• Corrosion-resistant，Can endure long-term corrosion in soils and water with varying pH levels.
• High-temperature and freeze-resistant, as well as aging-resistant.
• Excellent water permeability ,The gaps between fibers ensure good seepage performance.
• Microorganism-resistant ,Unaffected by microbes and insect damage.
• Easy construction, Lightweight and flexible material makes transportation, laying, and construction convenient.

Function

• Isolation：Separates materials like soil/sand or soil/concrete, preventing mixing and improving load capacity.
• Filtration：Lets water pass while blocking soil/sand particles, keeping structures stable.
• Drainage：Creates drainage paths in soil to remove excess water and gas.
• Reinforcement：Boosts soil strength and stability, reduces deformation.
• Protection：Shields soil from erosion by spreading water pressure.

Purpose

Short-fiber needle-punched geotextile is a widely used geosynthetic material. It is extensively applied in various engineering projects such as railway subgrade reinforcement, highway pavement maintenance, dam protection, hydraulic structure isolation, tunnels, coastal tidal flats, land reclamation, environmental protection, power plants, and airports.

• Filtration material for soil layer separation;
• Drainage material for reservoirs, mineral processing, and high-rise building foundations;
• Erosion control material for river embankments and slope protection;
• Reinforcement material for railway, highway, and airport runway subgrades, as well as swamp road construction;
• Thermal insulation material for frost and freeze protection;
• Anti-cracking material for asphalt pavements.
